GDP-mannose 4,6-hydro-lyase (GDP-4-dehydro-6-deoxy-D-mannose-forming)

The bacterial enzyme requires bound NAD+. This enzyme forms the first step in the biosynthesis of GDP-alpha-D-rhamnose and GDP-beta-L-fucose. In Aneurinibacillus thermoaerophilus L420-91T, this enzyme acts as a bifunctional enzyme, catalysing the above reaction as well as the reaction catalysed by EC 1.1.1.281, GDP-4-dehydro-6-deoxy-D-mannose reductase [5]. Belongs to the short-chain dehydrogenase/reductase enzyme family, having homologous structures and a conserved catalytic triad of Lys, Tyr and Ser/Thr residues [6].
